Tip: When viewing a conversation, you can automatically quote text in a comment by highlighting the text, then typing r. You can quote an entire comment by clicking , then Quote reply. For more information about keyboard shortcuts, see "Using keyboard shortcuts."

You can define relative links and image paths in your rendered files to help readers navigate to other files in your repository.

A relative link is a link that is relative to the current file. For example, if you have a README file in root of your repository, and you have another file in docs/CONTRIBUTING.md, the relative link to CONTRIBUTING.md in your README might look like this:

[Contribution guidelines for this project](docs/CONTRIBUTING.md)

GitHub will automatically transform your relative link or image path based on whatever branch you're currently on, so that the link or path always works. You can use all relative link operands, such as ./ and ../.

Relative links are easier for users who clone your repository. Absolute links may not work in clones of your repository - we recommend using relative links to refer to other files within your repository.

You can create a nested list by indenting one or more list items below another item.

To create a nested list using the web editor on GitHub or a text editor that uses a monospaced font, like Atom, you can align your list visually. Type space characters in front of your nested list item, until the list marker character (- or *) lies directly below the first character of the text in the item above it.

1. First list item
- First nested list item
- Second nested list item

To create a nested list in the comment editor on GitHub, which doesn't use a monospaced font, you can look at the list item immediately above the nested list and count the number of characters that appear before the content of the item. Then type that number of space characters in front of the nested list item.

In this example, you could add a nested list item under the list item 100. First list item by indenting the nested list item a minimum of five spaces, since there are five characters (100.) before First list item.

100. First list item
- First nested list item

You can create multiple levels of nested lists using the same method. For example, because the first nested list item has seven spaces (␣␣␣␣␣-␣) before the nested list content First nested list item, you would need to indent the second nested list item by seven spaces.

You can mention a person or team on GitHub by typing @ plus their username or team name. This will trigger a notification and bring their attention to the conversation. People will also receive a notification if you edit a comment to mention their username or team name.

@github/support What do you think about these updates?

When you mention a parent team, members of its child teams also receive notifications, simplifying communication with multiple groups of people. For more information, see "About teams."

Typing an @ symbol will bring up a list of people or teams on a project. The list filters as you type, so once you find the name of the person or team you are looking for, you can use the arrow keys to select it and press either tab or enter to complete the name. For teams, enter the @organization/team-name and all members of that team will get subscribed to the conversation.

The autocomplete results are restricted to repository collaborators and any other participants on the thread.

You can bring up a list of suggested issues and pull requests within the repository by typing #. Type the issue or pull request number or title to filter the list, and then press either tab or enter to complete the highlighted result.

Some GitHub Apps provide information in GitHub for URLs that link to their registered domains. GitHub renders the information provided by the app under the URL in the body or comment of an issue or pull request.
